Private because it can't be otherwise.

We did not promise to be careful with your files. We built it so we never receive them.

No upload, no server

There is no backend. The site is a set of static files, and your documents are processed in your browser's memory.

Fast and offline-ready

No queue and no round trip. Once a page has loaded, the tool keeps working with the network switched off.

Private by design

The tools make no network requests while they work, and every library is served from this domain. See the privacy policy for the few things that are measured.

Don't trust. Verify.

Check it in under a minute.

You shouldn't need to believe a privacy claim. Your browser can prove it.

  1. Open developer tools and go to the Network tab.
  2. Clear the list, then add a file to any tool.
  3. Watch the list stay empty. Then go offline and try again.
